An open textbook is a textbook licensed under an open copyright license, and made available online to be freely used by students, teachers and members of the public. Many open textbooks are distributed in other printed, e-book, or audio formats that may be downloaded or purchased at little or no cost.
Part of the broader open educational resources movement, open textbooks increasingly are seen as a solution to challenges with traditionally published textbooks, such as access and affordability concerns. Open textbooks were identified in the New Media Consortium's 2010 Horizon Report as a component of the rapidly progressing adoption of open content in higher education.
Usage Rights 
The defining difference between open textbooks and traditional textbooks is that the copyright permissions on open textbooks allow the public to freely use, adapt and distribute the material. Open textbooks either reside in the public domain or are released under an open license that grants usage rights to the public so long as the author is attributed.
- use the textbook freely
- create and distribute copies of the textbook
- adapt the textbook by revising it or combining it with other materials
Some open licenses limit these rights to non-commercial use or require that adapted versions be licensed the same as the original.
Open Licenses 
Some examples of open licenses are:
- Creative Commons Attribution (CC-BY) 
- Creative Commons Attribution Share-Alike (CC-BY-SA) 
- Creative Commons Attribution Non-Commercial Share-Alike (CC-BY-NC-SA)

Open textbooks increasingly are seen as an affordable alternative to traditional textbooks in both K-12 and higher education. In both cases, open textbooks offer both dramatic up-front savings and the potential to drive down traditional textbook prices through competition.
Higher Education 
Overall, open textbooks have been found by the Student PIRGs to offer 80% or more savings to higher education students over traditional textbook publishers. Research commissioned by the Florida State Legislature found similarly high savings and the state has since implemented a system to facilitate adoption of open textbooks.
In the Florida legislative report, the governmental panel found after substantial consultation with educators, students, and administrators that "there are compelling academic reasons to use open access textbooks such as: improved quality, flexibility and access to resources, interactive and active learning experiences, currency of textbook information, broader professional collaboration, and the use of teaching and learning technology to enhance educational experiences." (OATTF, p. i) Similar state-backed initiatives are underway in Washington, Ohio, California, and Texas. In Canada, the province of British Columbia became the first jurisdiction to have a similar open textbook program.
K–12 Education 
Research at Brigham Young University has produced a web-based cost comparison calculator for traditional and open K-12 textbooks. To use the calculator the inputs commercial textbook cost, planned replacement frequency, and number of annual textbook user count are required. A section is provided to input time requirements for adaptation to local needs, annual updating hours, labor rate, and an approximation of pages. The summary section applies an industry standard cost for print-on-demand of the adapted open textbook to provide a cost per student per year for both textbook options. A summed cost differential over the planned period of use is also calculated.
In November 2010, Dr. Anthony Brandt was awarded an "Access to Artistic Excellence" grant from the National Endowment for the Arts for his innovative music appreciation course in Connexions. "Sound Reasoning" "takes a new approach [to teaching music appreciation]: It presents style-transcendent principles, illustrated by side-by-side examples from both traditional and contemporary music. The goal is to empower listeners to be able to listen attentively and think intelligently about any kind of music, no matter its style. Everything is listening based; no ability to read music is required." The module being completed with grant funds is entitled "Hearing Harmony". Dr. Brandt cites choosing the Connexions open content publishing platform because "it was an opportunity to present an innovative approach in an innovative format, with the musical examples interpolated directly into the text."
In December 2010, open textbook publisher Flat World Knowledge was recognized by the American Library Association's Business Reference and Services Section (ALA BRASS) by being named to the association's list of "Outstanding Business Reference Sources: The 2010 Selection of Recent Titles." The categories of business and economics open textbooks from Flat World Knowledge's catalog were selected for this award and referenced as "an innovative new vehicle for affordable (or free) online access to premier instructional resources in business and economics." Specific criteria used by the American Library Association BRASS when evaluating titles for selection were:
A resource compiled specifically to supply information on a certain subject or group of subjects in a form that will facilitate its ease of use. The works are examined for authority and reputation of the publisher, author, or editor; accuracy; appropriate bibliography; organization, comprehensiveness, and value of the content; currency and unique addition to the field; ease of use for intended purpose; quality and accuracy of indexing; and quality and usefulness of graphics and illustrations. Each year more electronic reference titles are published, and additional criteria by which these resources are evaluated include search features, stability of content, graphic design quality, and accuracy of links. Works selected are intended to be suitable for medium to large academic and public libraries.
Because authors do not make money form the sale of open textbooks, several organizations have tried to use prizes or grants as financial incentives for writing open textbooks or releasing existing textbooks under open licenses. Connexions announced a series of two grants in early 2011 that will allow them to produce a total of 20 open textbooks. The first five titles will be produced over an 18 month time frame for Anatomy & Physiology, Sociology, Biology, Biology for non-majors, and Physics. The second phase will produce an additional 15 titles with subjects that have yet to be determined. It is noted the most expensive part of producing an open textbook is image rights clearing. As images are cleared for this project, they will be available for resuse in even more titles. In addition, the Saylor Foundation sponsors an ongoing "Open Textbook Challenge", offering a $20,000 reward for newly-written open textbooks or existing textbooks released under a CC-BY license.
The Text and Academic Author's Association awarded a 2011 Textbook Excellence Award ("Texty") to the first open textbook to ever win such recognition this year. A maximum of eight academic titles can earn this award each year. The title "Organizational Behavior" by Talya Bauer and Berrin Erdogan earned one of seven 2011 Textbook Excellence Awards granted. Bauer & Erdogan's "Organizational Behavior" open textbook is published by Flat World Knowledge.
One common frustration with traditional textbooks is the frequency of new editions, which force the instructor to modify the curriculum to the new book. Any open textbook can be used indefinitely, so instructors need only change editions when they think it is necessary.
Many open textbooks are licensed to allow modification. This means that instructors can add, remove or alter the content to better fit a course's needs. Furthermore, the cost of textbooks can in some cases contribute to the quality of instruction when students are not able to purchase required materials. A Florida governmental panel found after substantial consultation with educators, students, and administrators that "there are compelling academic reasons to use open access textbooks such as: improved quality, flexibility and access to resources, interactive and active learning experiences, currency of textbook information, broader professional collaboration, and the use of teaching and learning technology to enhance educational experiences." (OATTF, p. i)
Author compensation for open textbooks works differently than traditional textbook publishing. By definition, the author of an open textbook grants the public the right to use the textbook for free, so charging for access is no longer possible. However, numerous models for supporting authors are developing. For example, a startup open textbook publisher called Flat World Knowledge pays its authors royalties on the sale of print copies and study aids. Other proposed models include grants, institutional support and advertising.
Legislation "to authorize grants for the creation, update, or adaption of open textbooks" and assure those developed would be made available under favorable licenses was introduced into the 111th United States Congress, both in the Senate and the House of Representatives. Findings specific to open textbooks detailed in the bill text are:
- The growth of the Internet has enabled the creation and sharing of open content, including open educational resources.
- The President has proposed a new, significant Federal investment in the creation of online open-source courses for community colleges that will make learning more accessible, adaptable, and affordable for students.
- The President has challenged the United States with a goal of having the highest college graduation rate in the world by 2020.
- More than 80 percent of the 23,000,000 jobs that will be created in the next 10 years will require postsecondary education, but only 36 percent of all 18- to 24-year-olds are currently enrolled in postsecondary education.
- The high cost of college textbooks continues to be a barrier for many students in achieving higher education, and according to the Advisory Committee on Student Financial Assistance, 200,000 qualified students fail to enroll in college each year due to cost.
- The College Board reported that for the 2007-2008 academic year an average student spent an estimated $805 to $1,229 on college books and supplies.
- Making high quality open textbooks freely available to the general public could significantly lower college textbook costs and increase accessibility to such education materials.
- Open textbooks can improve learning and teaching by creating course materials that are more flexible, adaptable, and accessible through the use of technology.
This legislation did not reach the floor of either chamber for debate or vote prior to the conclusion of the 111th Congress.
Industry opposition 
The current higher education textbook industry has voiced stiff opposition to creation and adoption of open textbooks. The industry is represented by Bruce Hildebrand, a former Senior Vice President from the controversial firm Hill & Knowlton International Public Relations, who is now acting as Executive Director for Higher Education for the Association of American Publishers.
A number of projects seek to develop, support and promote open textbooks. Two very notable advocates and supporters of open textbook and related open education projects include the William and Flora Hewlett Foundation and the Bill and Melinda Gates Foundation.
